COMBINATION Toor. v n' Application filed December 31, 1927. Serial No.243,819.

This invention relates to tools or instruments of the General typedescribed and claimed in my etters Patent of the United States No.1,667,462 of April 24th, 1928.

Among the objects of the invention is to enlarge the field of usefulnessof this tool Yso as to provide for a more flexible interchange ofinstrument blades or attachments with respect to a common handle and tofacilitate such interchange in an easy practical manner.

More deiinitely stated, the general object and scope of this inventionis comprehended in aconstruction involving a handle, a tool or-bladesocket in the nature of a hub journaledy permanently in said handle soas to be swung into open or closed positiomand a Series of blades,tools, or other instrument-alities adapted to be inserted selectivelyand 0 interchangeably into said socket piece or hub.- 1

With the foregoing andother objects'in viewV the invention consists inthe arrange- Y 2F ment and combination of parts hereinafter 0 describedand claimed, and while the invention vis not restricted to the exactYdetails of construction-disclosed or suggested herein, still for thepurpose ofV illustrating a practical embodimentl thereof reference ishad .to `the accompanying dra-wings in which like reference charactersdesignate the same parts inthe several views, and in which-f Figure 1 isa plan view of a blank from which a preferred form of the handlemechanism may be formed from sheet metal. Y

Fig. 13 is -a side view of-a different type of; blade. Y

. Fig. 14v is -a still further form of inter'- changeableblade or tool.

Referring now ,more specifically to the" drawings, l show a handle 15-formed as v shown inV Fig. `1 from a sheetV metal blank having twocheek plates 15a and 15b foldable into parallel planes-,along'a yback orrib 16 and provided Vwit-hregistering holes *17" and 18 at or near itsopposite ends', lthe holesV 17 for a hanger or link 19, and the otherholes-fora pivot pin`20. These cheek plates are spaced from eachl otheras shown in Fig. 8. rlhe pivot-end ofthe handle is formed on arcs ofcircles at 21approXimately concentric with the pivot holes 18, and theadjacent end of the rib 16 constitutes ashoulder at 22.

'lhe hub or socket member of Figs. 3,4, 5, and 7 is shown as a whole at23 and comprises two substantially similar cheek 'plates or disks 24having registering holes 18a and 80 a central connecting web 25 which inthe iinished structure, as shown in-Figs. 4 and 7, constitutes ashoulder adapted to abut against the shoulder 22'in the open position ofthe instrument. lt will be understood thatl the socket member is soformed as to provide an open space or socket .26 bounded on one; sidebythe shoulder web 25 and-onthe oppositeside by a closed web 27. Also itwill be Y noted that the socket member otherwise is "i approximatelycircular and with the pivot holes 18a central thereof and adapted toregister with the pivot holes 18 of the handle and through all of whichholes the ypivot pin 20tpasses fastening'the handle and socket 95 y"member permanentlytogether. The socket lnemberis of relatively thinstructure andl operates inthe lspace between the side plates or` cheekpieces 15a and 415b ofthe handle. These two parts may be held from freerela- 10 tive rotation by friction or any other suity able means, as,for instance, the positive lock- The parts are so made that they areretained normally in connection by friction, but they may be separatedby drawing the two parts directly away from each other. Fig. 13 shows adifferent type of blade in the nature of a surgeons lance 32 provided,however, with a similar socket and slot 31 for the Y purposes statedabove. The preferred form,

however, of detachableA or interchangeable instrumentality is shown inFig. 9 .which constitutes a holder 33 of sheet metal formed f from theblank as shown'in Fig. 12 and comprising two side portions 34 and 35, atleast one of which is provided with anintegral shank xportion 30a havinga slot 31. At the end ofthefholder 33 remote from the shank there isprovided a locking pin 36, and while the main portions tof the sides 34and 35 may be Vapproximately parallelto each other and slightly spaced,they are preferably swaged inward toward each other at their midportions as shown at 37 for the purpose of grippingtightly upon thesides of a blade 38 adapted for co-operation with such holder.

'Ihel blade 38 has a sharp cutting 'edge 39 and is made preferably ofsubstantially rectangular form but provided at its ends` with a pair ofnotches 40 and 41, each end design being a duplicate of the other. Theblade body is made preferably of uniform thickness and approximating thenormal space between the side pieces 34 and 35 of the holder but greaterin thickness than the space at the swaged portion 37. With either end ofthe blade inserted into the holder as shown in dotted lines in Fig. 9,the notch 40 at'such end-will receive the pin as an anchor meansor'fulcrum and then the back edge of the blade will be forced directlyinto the channel of the holder where it will be gripped snugly as shownin Figs. 9 and 11 and where the device may be used as a sharp cuttingknife or scraper when the holder shank 40a is inserted into the socketpiece 23. Theholder; and blade therein maybe swung around into'- thehandle in a mannersimilar to the action of a knife blade in an ordinaryknife handle for carrying purposes and swung outward into open positionfor cutting purposes. The hole or, notch 40 at the opposite end of'the'blade from theone already described is normally idle but the notch41 adjacent thereto is employed vfor the application of a pry tool orinstrument such as a small coin indicated at C in Fig. 9 which may beinserted between the end of the blade and the adjacent end of the handlefor the purpose of starting the blade outwardfrom the holder' for thepurpose of turningthe blade end to end or` for the interchange of oneblade for another. Obviously when one end or point of the blade 38becomes dulled the other end may be turned for use by removing the bladeas just described and lturning it end to end and inserting it as beforedescribed. Fig. v1li gives a suggestion of a still furthermodificationfof instrumentalities, the same comprising a holder 33a inthe nature of asafety razor guard and adapted to receive and hold. -anysuitable bladefor shaving or other pur-- poses,-but providedwith a shank30?) having .a notch orslot 31 made Ato conformV to the socket 26 in thesocket piece in'whichit'is adapted to be used interchangeably the sameas all the otherA devices set forth herein. It will be understood thatmany other forms of blades or tools may be used in this manner providedthey are provided with shanks adapted ,to fitiinto the socket pieceinter changeably. I As la commercial propositiom.

these handles, socket pieces, and blade instrumentalities are made insets so that a single handleA and socketpiece may be used for anydesired number of blades interchangeably..

I claim: v 1. Ina combination tool, a handle, ahub 4 loof in the handlefor engaging a tool means, said hub c onsistingof a single sheet of`material comprising a plurality of che'ekplates inter-v connected byarweb, another oppositely positioned split web, and pivot means passing'through the cheek plates and mounting the hub on the handle, one of saidwebs coacting with the handle as a stop.

V2,. In a combination tool,a handle having a circular end, pivotmeans-thereon at said end, a hub on the pivot means, said hub consistingof a single piece of sheet material comprising a plurality of cheekplates interconnected by a web, and means including a tool holderhaving'a slotted end received in the hub, and with the slot receivingthe pivot means, said tool holder having pin means at the free endthereof, and a blade positioned in the said holder, said blade Vhaving arecess at one endto engage the'pin' means, and

a recess at its oppositeend adjacent to the center line of the handlethrough the center ofsaid circular end, thelast mentioned recess beingoutside of the tool holder whereby the blade may be pried out thereofwith the circular end of the handle acting as a pivot.

3. Ina combinationtool, a handle, pivot f means thereon, a hub on thepivotmeans, said hub comprising arplurah'ty of cheek plates,interconnected by a web, and'means including a tool holder having aslotted end received in the hub, and With the slot receiving the pivotmeans, said tool holder having pin means at the free end thereof, and ablade positioned in the said holder, said blade having a recess at oneend to engage the pin means, and a recess at its opposite end normallyexposed from the holder to permit of engagement of the blade for removalthereof, the body of the holder being to one side of the axis of thehandle,the end of the blade adjacent to the handle being spacedtherefrom d for easy access of the exposed recess and to permit theapplication of a pry thereto with the adjacent end of the handle actingas a pivot.

In testimony whereof I aiix my signature.

GEORGE A. LOGAN.
